Line 3 Replacement Program (Canada)

The multibillion-dollar Line 3 Replacement Program (L3RP) is the largest project in Enbridge history. The new Line 3 will comprise the newest and most advanced pipeline technology—and provide much needed incremental capacity to support Canadian crude oil production growth, and U.S. and Canadian refinery demand.

On the Canadian side of the border, Enbridge Pipelines Inc. has announced plans to undertake an approximately $5.3-billion replacement program for most of its Line 3 pipeline running between Hardisty, Alberta and Gretna, Manitoba.

The L3RP will replace the existing 34-inch-diameter pipeline with new 36-inch-diameter pipe, using the latest available high-strength steel and coating technology, while the existing segments will be removed from operation.

Replacing the pipeline is the most efficient way to maintain the reliability of Line 3, and it’s also the most timely and reliable transportation solution for transporting Western Canadian crude oil to refinery markets in Chicago, the U.S. Gulf Coast, and the Eastern U.S. and Canada.

Enbridge’s traffic accommodation strategies—which must be followed by our employees and contractors—are designed to minimize disruptions, and protect residents and workers, during the pipeline construction process.

With proper design, construction, operation and maintenance, pipelines have a very long life. The safety of people, and protection of the environment, is our top priority throughout the entire pipeline lifecycle.

After construction of energy infrastructure, Enbridge's goal is to restore the affected area (including pipeline rights-of-way) to as close to pre-construction condition as possible, and minimize our long-term impact to the land.
